Martech Leader RadiumOne Raises $54 Million Round to Drive Continued Technology Innovation


SAN FRANCISCO, CA  June 30, 2015 RadiumOne, a leading marketing technology platform that drives outstanding performance for the world’s largest brands and agencies, announced today that it has secured $54 million in equity and debt financing led by Harmony Partners with participation from Industry Ventures and existing investors Adams Street Partners, Crosslink Capital, Trinity Ventures, and DFJ Esprit.

RadiumOne, which is profitable, achieved its strongest financial performance in its history in the second half of 2014. With Q1 2015 officially its second best revenue quarter and Q2 revenue expected to be its best quarter ever, the company is on track to far exceed its 2015 goals.

Bill Lonergan, CEO of RadiumOne, attributes RadiumOne’s success to its proprietary data, natively integrated technology platform, and software tools. “There is a rush of digital advertising spending coming into the marketplace,” said Lonergan. “RadiumOne is uniquely poised to capture more of the market and lead the industry because we have a unique way of reaching large-scale audiences, in real-time, across every digital touchpoint, generating new customers for our clients. These prospects are in the market to buy our clients’ products, and whether it’s through managed service or self-serve tools, we deliver outstanding advertising performance that helps our clients grow their businesses. This added capital allows us to further invest in innovative technology, prepare for future advertising opportunities, and serve growing ad markets around the world.”

With the proceeds from this financing, RadiumOne plans to increase investment in Activate, its market-leading self-service and managed-service programmatic advertising platform; continue expanding its global reach into Asia-Pacific and Europe; and further develop its patented big data and software solutions that analyze consumer social sharing behaviors. The company has now raised more than $87 million in debt and equity.

“We’re partnering with RadiumOne at a pivotal and exciting time in the company’s trajectory,” said Mark Lotke, Managing Partner and Co-Founder of Harmony Partners. “The company’s leadership has generated impressive business gains and returns, with each successive quarter outperforming the previous one. As more media channels are being bought and sold programmatically, RadiumOne’s incredible momentum is a sign of the bright future for digital advertising.”

RadiumOne now serves over 1,000 customers across 12 countries, with clients in the travel, financial services, retail, telecom, automotive, and entertainment sectors.

“Marketers are continuing their march toward programmatic – not just with online, video and mobile display ads but with rich media formats as well,” said Lonergan. “In fact, eMarketer estimates that US programmatic digital ad spending, including both display and video, will grow to $24 billion by 2016. Given our omni-channel approach, we believe brands and agencies will continue to view RadiumOne’s differentiated platform as the go-to destination for creating targeted, efficient, and effective marketing campaigns.”

RBC Capital Markets acted as exclusive placement agent for this financing.
